Question

can someone quickly show me how to determine if this graph of an equation is symmetric to y=-x or y=x?

Answer 1

such as xy=12 or y= +- radical x+6

Answer 2

what are the conditions for y = -x or y =x ?

Answer 3

if you plug in x for y and y for x, they should be the same? and if you plug in -x for y and y for -x, the same?

Answer 4

??

Answer 5

and how would i know the point is symetrical to the point (3,-8) ato the line x=7?

Answer 6

i only know how to find x axis, y axis and origin symmetry

Answer 7

pls help?

Answer 13

If the point (a,b) is on a graph and the point (b,a) is on another graph, then the two graphs are symmetrical about the line y = x.

Answer 14

what's the line y=x?

Answer 15

how can i test it on a equation?
